This may adversely affect environment, human health, other life forms, even after a sophisticated treatment for decontamination. All dental professionals therefore, should follow “best management practices” in the handling and disposal of waste to reduce potential environmental effects

Methodology: Dental professionals with minimum of six months of work experience responded to a self–administered questionnaire regarding awareness of best management practices for dental waste water. Questionnaire was divided into different subcategories of waste entering water stream. A scoring pattern was instituted for ease of analysis.
